I consider the most effective part of using pen and paper for developing my another great-but-vague-formulated-idea is that if I write something down then in few minutes I am having a lot of different facts on my sheet. I look at the sheet and produce a new extension of my idea which might be way harder without seeing that much of disturbing me facts at once. And I never reread my notebooks full of notes, because after some extension has developed, all previous writings use to become stupid-looking and outdated because they do not have the extension.
